Piers Anthony has written in early challenges of using computer into a ton of his stories. Xanth had ComPewter, which could magically re-write reality just by "announcing it". In that universe, magic was especially concerned about the role of Might Makes Right and whether only someone with Magician grade talent deserved to rule Xanth. I lost track if ComPewter ever both got past the non-human aspects of things to be certified "Magician grade". It's not on this list from Wikipedia.
